This is about decoupling the sending of a query and retrieving hits.  E.g.,

RunQueryCommand <-- asks remote nodes to run a query.  Request contains a unique query ID?  Maybe a UUID?
GetHitsCommand <-- asks for some hits.  Command contains the query ID, and number of hits being asked for.  (-1 = all hits?)  This command returns with a list of commands + a flag telling the caller whether there are any more hits left from the node.

This is just a basic idea.  I'm sure you can distil it further and improve on it.  :)
